PHP AES CBC encryption, decryption function PHP AES mcrypt PHP AES ECB PHP java AES Encryption solution

/*

* $data encrypted content, $key key

*/

function Cbc_encrypt ($data, $key) {

$iv = $key;
$padding =-(strlen ($data)% 16);
$data. = Str_repeat (Chr ($padding), $padding);
$encrypted = Mcrypt_encrypt (mcrypt_rijndael_128, $key, $data, MCRYPT_MODE_CBC, $IV);
Return Base64_encode ($encrypted);
}
function Cbc_decrypt ($data, $key) {
$iv = $key;
$data = Base64_decode ($data);
$data = Mcrypt_decrypt (mcrypt_rijndael_128, $key, $data, MCRYPT_MODE_CBC, $IV);
$padding = Ord ($data [Strlen ($data)-1]);
Return substr ($data, 0,-$padding);
}

The above describes the PHP AES CBC encryption, decryption functions, including the php,aes aspect of the content, I hope the PHP tutorial interested in a friend to help.
